David Whitmer, Martin Harris, and Oliver Cowdery. Those are the well-known names of three men whose witnesses of the Book of Mormon stood the test of time, even if their loyalty to the Church sometimes wavered. But who were they? What about these men enabled God to use them in Restoration? Why did they all, at various points, step away from the Church? And why did two of them come back? On this week’s episode, Daniel Peterson, an executive producer of the new movie “Witnesses,” discusses the significance of these men’s roles in Church history and why we should hold gratitude in our hearts for their lives.
